Abstract

See full text

To provide a solid catalyst component for olefin polymerization having a small amount of fine powder. A solid catalyst component for olefin polymerization containing a titanium atom, a magnesium atom, a halogen atom, and an internal electron donor. The solid catalyst component has an absolute difference in binding energy of 73.50 to 75.35 eV between a peak (1) with the binding energy of 457.00 to 459.00 eV and a peak (2) with the binding energy of 532.50 to 534.50 eV. The peak (1) and the peak (2) are within peak components measured by X-ray photoelectron spectroscopy, the peak (1) is obtained by waveform separation of peaks assigned to the 2p orbitals of the titanium atom, and the peak (2) is obtained by waveform separation of peaks assigned to the is orbital of an oxygen atom.
